Definitions
- the invention relates to a cutting tool having a base body extending along a longitudinal central axis or axis of rotation, at least one blade carrier arranged radially adjustably on the base body and an adjusting device for adjusting the position of a blade carrier relative to the base body.
- a cutting tool specified in DE 4022579 A1 has a base body which can be driven in rotation about an axis of rotation and a blade carrier which is arranged so as to be radially adjustable on the base body and carries a cutting tool.
- the blade carrier is designed as a two-armed pivoting beam, which is arranged in a pivotally mounted in the main body to the rotational axis pivot bearing under radial displacement of the arranged on the one lever arm of the pivoting beam cutting tool, in particular an indexable insert, pivotally.
- control rod in DE 4022579 A1 The adjustment of the blade carrier via an adjusting device which has an axially displaceably arranged in the main body actuating rod (referred to as control rod in DE 4022579 A1), which has at an axial distance from each other two, in opposite directions opposite the rod axis obliquely employed control surfaces on each one of the lever arms via a in the
- Main body substantially in the feed direction of the cutter support displaceable pressure pin is applied.
- the adjusting device allows an adjustment of the cutter carrier between a controlled position, in which the cutting tool held on the cutter support is at a minimum diameter, and a controlled position, in which the cutting tool held on the cutter carrier to a maximum diameter by a werkzeugmaschi- side effected displacement of the actuating rod lies.
- a gene arranged the end face of the associated pressure pin adjustable adjusting screw (in DE 4022579 A1 as adjusting bolts).
- the adjusting screw allows an adjustment of the cutter support relative to the longitudinal central axis or axis of rotation of the main body or the adjusting rod in the main body.
- the adjusting screw forms with the threaded bore an integrated into the blade carrier adjustment for an individual position adjustment of the blade carrier relative to the longitudinal central axis or axis of rotation of the body. Beyond this position adjustment, which usually takes place within a very narrow adjustment range, the position of the cutter carrier can not be adjusted further.
- a pressure spring packet is arranged between the adjusting screw on the one hand and the pressure pin on the other hand.
- the spring package should ensure that, despite the manufacturing inaccuracies always backlash in the adjustment mechanism is guaranteed.
- the spring assembly exerts on the screw from a pressure force through which, seen in the pressure force direction, front thread flanks of the adjusting screw are pressed against the opposite thread flanks of the threaded hole. In this respect, a thread play between the front thread flanks of the set screw and the opposite thread flanks of the threaded hole is reduced.
- the invention is based on the object of providing a cutting tool with a central adjusting device, with which a precise position adjustment of a cutter carrier can be reliably and simply carried out in order to achieve a high diameter accuracy of a tool cutting edge.
- a cutting tool according to the invention which can be operated standing or rotating, has, analogously to the cutting tool known from DE 4022579 A1, a main body extending radially along a longitudinal central axis or rotation axis, at least one blade carrier radially adjustable on the main body and a central adjusting device for adjusting the Position of the blade carrier relative to the base body.
- An example of such a cutting tool is a fine boring tool for boring and reworking an already prefabricated bore, as shown and described for example in the initially discussed DE 4022579 A1.
- the blade carrier can cooperate with the central actuating device arranged in the main body via a wedge gear.
- the above-mentioned blade carrier generally refers to a unit, a part, a body, a means or the like that carries, directly or indirectly, one or more cutting edges for machining a workpiece.
- An inventive blade carrier can, for example, in the manner of a rocker or a pivoting beam as a two-armed lever pivotally held on the base body, for example on the model of the initially discussed DE 4022579 A1, or in the manner of an elastically deformable bending beam held on the body, for example as a so-called clamp , in particular Kurzklemmhalter, be formed and a cutting tool, such as a cutting insert, an insert or the like, with a or several cutting edges.
- a blade carrier according to the invention can also be formed from a cutting tool constructed in one piece or integrally, for example in the form of a turning tool, a cutting insert, an insert or the like and one or more cutting edges for a machining of a workpiece - directly - wear.
- the adjusting device of a cutting tool now has a threaded sleeve rotatably fixed in the base body, but axially displaceable, and a threaded drive driving the threaded sleeve.
- the threaded sleeve can interact with the blade carrier via a wedge gear.
- the threaded spindle can be actuated from the front side of the main body.
- the operation can be done manually or machine tool controlled.
- a rotationally movable at the front end of the body, but held axially fixed actuator can be provided which is rotationally fixed, but axially movable in engagement with the threaded spindle.
- the threaded sleeve displacing screw drive allows axial displacement, the blade carrier between a controlled position, in which the cutting tool held on the cutter support is at a minimum diameter, and an extended position, in which the blade held on the cutter support cutting tool is at a maximum diameter, to adjust len.
- the screw drive therefore allows an accurate fine adjustment of the blade carrier independent of an adjustment between the controlled position and the controlled position.
- Such an adjustment of the cutter carrier between a controlled position in which the cutting tool held on the cutting tool is at a minimum diameter, and a staggered position in which the blade carrier held on the cutting tool is at a maximum diameter can be realized, for example, that the screw is connected to a piston arranged in a pressure chamber in the main body.
- the piston can be elastically, preferably resiliently, supported relative to the main body.
- the screw can have a screwed with the threaded sleeve threaded spindle.
- This threaded spindle can be connected, for example, with the above-mentioned piston, but this is not mandatory.
- the threaded spindle can be formed from a differential threaded spindle.
- the screw drive may further comprise a arranged between the threaded sleeve and the piston bearing bush, for example, with the above-mentioned piston tensile / pressure-tight manner, and the differential threaded spindle having a first threaded portion with the threaded sleeve and with a second threaded portion with the Bearing be bolted.
- an adjusting device assigned to the cutter carrier can furthermore be arranged, which allows an individual position adjustment of the blade carrier relative to the base body.
- This adjusting device can have an integrated into the blade carrier threaded bushing with a radially elastic deformable wall segment, a bolted to the threaded bush and supported with its outstanding by the threaded end end of the threaded sleeve adjusting screw, and arranged on the cutter support, the wall segment against the screw pushing pressure element.
- This adjustment is based on the idea that by pressing the elastically yielding wall segment of the threaded bushing a wall segment corresponding portion of the internal thread of the threaded bush is pressed in a direction transverse to the bush axis against the external thread of the screwed into the threaded bushing screw, whereby the thread play between the reduce the wall segment corresponding portion of the internal thread of the threaded bushing and the external thread of the screw in both axial directions.
- the elastically yielding wall segment may be formed by a slot penetrating the threaded bushing wall, in particular a substantially U-shaped slot.
- the wall segment may extend in the axial direction of the threaded bushing.
- the threaded bush for fixing to the base body, cutting tool, blade carrier or the like at its one end may have a stop forming flange. The position of the threaded bush in the direction of the bushing can be determined via the flange.
- the threaded bushing can be arranged in a through hole in the blade carrier, which permits an actuating access to the adjusting screw from the side facing away from the base body, for example radially from the outside.
- the threaded bushing can be fixed in the blade carrier in the axial and / or circumferential direction of the through hole in a material, positive and / or non-positive manner.
- An inventive cutting tool may have a plurality of cutting carriers, which are arranged at predetermined, preferably equal, angular intervals around the axis of rotation around and each supported on the threaded sleeve.
- a synchronous adjustment and / or adjustment of all cutter carriers can be effected via the central setting device.
- each cutter carrier can be adjusted by means of an associated adjusting device.

- FIG. 4 shows a perspective side view of a cutting carrier carrying a cutting tool
- FIG. 1 shows a perspective side view of a multi-bladed cutting tool 10, which is used, for example, for machining a cylinder bore of an internal combustion engine.
- the cutting tool 10 may therefore also be referred to as a cylinder bore machining tool or generally as a bore post-machining or bore finishing tool.
- the cutting tool 10 has a main body 12 extending along a longitudinal center axis or axis of rotation 1 1, which in the embodiment shown is constructed modularly from a front part and a rear part. As shown in Fig. 1, the front part 12a and the rear part 12b are bolted together. At its rear end (on the right in FIG. 1), the cutting tool 10 has a connection with a machine tool spindle, for example.
- Denden coupling shaft 13 which is formed in the illustrated embodiment of a HSK (hollow shaft taper) shaft. Alternatively, however, for example, a so-called SK (steep taper) shaft or the like may be provided.
- the cutting tool 10 can be used standing or rotationally driven.
- each cutter carrier 14 carries a cutting tool 15, for example a cutting insert, an insert or the like, and is adjustable radially inwardly or outwardly via a central actuating device 16 to be seen in FIG. 2 in synchronism with the respective other cutter carriers 14.
- each blade carrier 14 is individually positionally adjustable via an associated adjusting device 17 in the radial direction relative to the central adjusting device 16 or to the longitudinal central axis or axis of rotation 11 of the base body 12.
- the blade carriers 14 are all distinguished by the same construction and the same mode of operation, so that in the following the construction and the mode of operation of the blade carriers 14 will be described in more detail using the example of the lower blade carrier 14 shown in FIG.
- the blade carrier 14 shown on a larger scale in FIG. 4 essentially has a carrier body 18, the cutting tool 15 held on the carrier body 18, a clamping claw 19 for clamping the cutting tool 15, a clamping screw 20, the adjusting device 17, a spring stop screw 21, a compression spring 22 , a bearing pin 23 and a locking screw 24.
- the support body 18 is made of a prismatic o- or block-shaped block extending in a in the direction of the longitudinal central axis or axis of rotation 1 of the body 12 extending prismatic or cuboid, front and outer peripheral side receiving pocket 25 in Base body 12 is received, which is formed at a radial distance to the longitudinal central axis or axis of rotation 1 1.

- the cutting tool 15 is, as shown in Fig. 4, positively received in a incorporated in the support body 18 front and outer peripheral side accessible seat 27 and is clamped by pressing the clamping screw 20 via the clamping claw 19 against the support body 18. Adjustment device 16
- the central actuating device 16 has, as shown in Fig. 2, a threaded body 28 arranged in the base body 12 and a threaded sleeve 28 axially displacing screw 29.
- the threaded sleeve 28 forms a radial adjustment of the blade carrier 14 effecting actuating means. It is rotatably in a central bore 29a in the base body 12, but arranged axially displaceable and acts via a wedge gear with the cutter holders 14 together.
- the threaded sleeve 28, as shown in FIG. 3 has on its outer circumference a number of support strips 30 corresponding to the number of the blade carriers 14.

- Each pressure pin 26 is arranged radially displaceably in a guide bush 32 fixed in the base body 12.
- the control slope 31 forms with the end face of the pressure pin 26, the above-mentioned wedge gear, which converts an axial movement of the threaded sleeve 28 in a radial movement of the pressure pin 26.
- the rotationally fixed arrangement of the threaded sleeve 28 in the central bore 29a in the base body 12 is achieved by engaging in an axial longitudinal slot 33 on the outer circumference of the threaded sleeve 28 locking pin 34 which is releasably held in a radial stepped bore 35 in the base body 12. As shown in FIG.
- the screw 29, in particular the bearing bush 40, zug- / d jerk-proof with the aforementioned piston 42 is connected.
- the piston 42 is rotatably in a piston bore 43 in the base body 12, but arranged axially displaceable. It can be seen in Fig. 2 that the piston bore 43 is connected via a connecting bore 46 with the central bore 29 a.
- the step-like piston 42 has a piston extension 41, which penetrates the connecting bore 46 and in the region of the central bore 29 a rotatable and tensile / pressure-resistant manner with the bearing bush 40 is connected.
- the non-rotatable arrangement of the piston 42 in the piston bore 43 is achieved by a locking pin 47, which in an axial
- a compression spring 53 is tensioned, which urges the piston 42 in Fig. 2 to the right.
- the compression spring 53 is supported on a step 54 formed between the connecting bore 46 and the central bore 29a.
- the compression spring 53 is supported on an annular surface 55 surrounding the piston extension 41 of the piston 42.

- the actuation element As can be seen in FIG. 1, has a graduated ring 60, which makes possible a verifiable rotation of the actuation element 57 and thus of the threaded spindle 39.
- the supported on the control slopes of the threaded sleeve 28 cutter carrier 14 can therefore be adjusted by a manual or machine tool side accomplished rotary actuation of the actuator 57 synchronously to a predetermined nominal diameter.
- This presetting can be done in the shown in Fig. 2 controlled state of the blade carrier 14, in which the cutting tools 15 are at a maximum diameter.
- the default can also be done in an activated state of the blade carrier 14.
- the blade carriers 14 are in each case aligned with respect to the base body 12, in particular the central actuating device 16 arranged in the base body 12, in a positionally adjustable manner.
- Each cutter carrier 14 is associated with an individually operable adjusting device 17, via which the cutter support 14 and thus held on the cutter support 14 cutting tool 15 relative to the base body 12, in particular the longitudinal center axis or axis of rotation 1 1, are radially adjustable.
- the integrated on the side of the longer lever arm in the support body 18 adjusting device 17 has a wall segment slotted threaded bushing 61 in a substantially radially extending threaded bushing bore 62 in the support body 18 material, force and / or positive fit, with respect to the bore axis of the threaded bushing 62nd is rotatably and axially fixed, a screwed into the threaded bushing 61 screw 63 which cooperates via the aforementioned pressure pin 26 with the corresponding control slope 31 of the threaded sleeve 28, and in Fig.
- the clamping screw 64 receiving threaded bore 65 is accessible via a larger diameter engaging bore 67 in the base body 12 from the outer periphery of the body 12 ago.
- the diameter of the engagement bore 67 in the body 12 may be so large that the against the wall segment 66 of the threaded bush 61 pressing clamping screw 64 in any pivot position of the cutter support 14 by means of a guided through the engagement hole 67 tool key which engages in a wrench size of the clamping screw 64, is operable.
- the diameter of the engagement bore 67 may also be only so great that a tool key guided through the engagement bore 67 can be inserted into the wrench size of the tensioning screw 64 only for a predetermined pivoting region of the blade carrier 14.
- the threaded bush 61 has a flange
- Integrating the adjusting device 17 into the carrier body 18 results in a compactly constructed cutter carrier 14 which, with the integrated adjusting device 17 and the cutting tool 15, can be handled as an exchangeable component and attached to the main body 12 of the cutting tool 10.
- the adjusting device is integrated in the blade carrier. This is particularly advantageous when a central control device is provided. That does not have to be that way. If the cutting tool has no central adjusting device, the adjusting device can be integrated either in the blade carrier or in the main body. It is only crucial that the adjusting device is arranged functionally between the cutting tool and the base body.
- the screw with the main body or the blade carrier indirectly, for example, as in the embodiment described above, or interact directly.
- each blade carrier is arranged rocker-like in a receiving pocket on the base body.
- each blade carrier can also be designed in the manner of an elastically deformable bending beam and firmly screwed into a receiving pocket on the base body of a cutting tool.
- each blade carrier can be held radially displaceable in a receiving pocket on the base body of a cutting tool.
- the indications used above (in the radial direction) "on / off controllable”, “on / off”, “on / off control” etc. are therefore generally to be understood in the sense that the one or more blade carriers (in the radial direction) adjustable, wherein the adjustment can be done by pivoting (as in the embodiment shown), by elastic deformation or by linear displacement of the respective blade carrier.
- the pressurization of the piston takes place fluidically, in particular pneumatically or hydraulically.
- the pressurization of the piston may be initiated by an electric motor or electromagnetically.
- the cutting tool can therefore have a hydraulically, pneumatically, electromotively or electromagnetically operating actuator which drives the piston.
- the provided on the threaded sleeve control surfaces can be incorporated directly into the threaded sleeve material. This means that the support strips can be omitted. Furthermore, instead of individual control surfaces, the threaded sleeve can have a rotationally symmetrical conical surface on which the one or more cutting carriers are or are supported indirectly or directly.
